Jason Dusek disturbed my sleep to write: > 5 # mount /dev/acd0 /cdrom > mount: /dev/acd0: Input/output error You may want to try: mount -t cd9660 /dev/acd0c /cdrom or its equivalent: mount_cd9660 /dev/acd0c /cdrom Also, if you're trying to mount a DVD instead of a CD, you may need to try: mount_cd9660 /dev/cd0c /cdrom > I have some another disk mounting question, too.

What does it mean in reference to a CD drive? The superblock is a chunk of disk that has housekeeping information like the amount of free space, where to find free inodes, and so on. The error can mean pretty much the same things no matter what the medium. It might mean that you've specified the wrong filesystem -- "mount" (which defaults to FreeBSD's UFS filesystem) instead of "mount -t cd9660", say. It might also mean that the the filesystem hasn't been formatted yet, or (if a CD) that you've burned a coaster. Or, it might mean that you are about to be very grateful for your carefully-followed backup plan. :-) -- Saint Aardvark the Carpeted aardvark@saintaardvarkthecarpeted.com Because the plural of Anecdote is Myth.
